Synonyms: peptide boronate | PS-341 | Velcade®
bortezomib is an approved drug (FDA (2003), EMA (2004))
Compound class: Synthetic organic
Comment: Bortezomib is a dipeptide (Phe-Leu), with a pyrazinoic acid protecting the N-terminus and a boronic acid replacing the C-terminal carboxylic acid. The boron atom is believed to interact with and inactivate the catalytic site on β subunits which form the active core of the proteasome, preferentially binding β5 active site . Bortezomib is the first-in-class proteasome inhibitor to be approved for clinical use.
Proteasome activity is reviewed in .
The compound also has antimalarial activity. The Malaria tab on this ligand page provides additional curator comments of relevance to the Guide to MALARIA PHARMACOLOGY.
Ligand Activity Visualisation Charts
These are box plot that provide a unique visualisation, summarising all the activity data for a ligand taken from ChEMBL and GtoPdb across multiple targets and species. Click on a plot to see the median, interquartile range, low and high data points. A value of zero indicates that no data are available. A separate chart is created for each target, and where possible the algorithm tries to merge ChEMBL and GtoPdb targets by matching them on name and UniProt accession, for each available species. However, please note that inconsistency in naming of targets may lead to data for the same target being reported across multiple charts.✖
|Bortezomib inhibits activity of both the constitutive proteasome and the immunoproteasome, primarily through interaction with the β5 subunit of the former and the low-molecular mass polypeptide-7 (LMP7) which replaces β5 in the latter. Some clinical efficacy has been detected in patients with systemic lupus erythematosus [1,9,11] and other autoimmune disorders [5-6].|
